Today and tomorrow, TCM is saluting the centennial of the invention of Technicolor. The tribute begins at 6 a.m. ET Tuesday with a showing of the first feature-length color film, 1922’s The Toll of the Sea (before that, Technicolor was used sparingly, and mostly in shorts). Colorful examples of the pioneering color process are available all day and night today and Wednesday. Among the Day 1 highlights is this 1938 Michael Curtiz-direction action film, starring Errol Flynn as Sir Robin of Locksey – a.k.a. Robin Hood – and Olivia De Havilland as Maid Marian. Co-stars include Basil Rathbone, Claude Rains (who would work with Curtiz again, a few years later, on Casablanca), and, as the imposing Little John, Alan Hale – whose son, Alan Hale Jr., would end up playing the Skipper on Gilligan’s Island.
